1) y = (x - 2)²
Axis of Symmetry is x = 2
Vertex: (2, 0)
Opens up or down? Up
Slope to point one unit from the vertex: 2
y-intercept: 4
2) y = -3x² + 5
Axis of Symmetry is x = 0
Vertex: (0, 5)
Opens up or down? Down
Slope to point one unit from the vertex: -6
y-intercept: 5
3) y = 2(x + 1)² - 3
Axis of Symmetry is x = -1
Vertex: (-1, -3)
Opens up or down? Up
Slope to point one unit from the vertex: 4
y-intercept: -1
4) y = -2(x - 2)² - 3
Axis of Symmetry is x = 2
Vertex: (2, -3)
Opens up or down? Down
Slope to point one unit from the vertex: -8
y-intercept: -11
5) y = -(x - 3)² + 2
Axis of Symmetry is x = 3
Vertex: (3, 2)
Opens up or down? Down
Slope to point one unit from the vertex: -6
y-intercept: -7
6) y = -(x + 2)² + 1
Axis of Symmetry is x = -2
Vertex: (-2, 1)
Opens up or down? Down
Slope to point one unit from the vertex: -4
y-intercept: -3
